“…The larvae of E. tages were associated with south-facing slopes, whereas their foodplant (L. corniculatus) was associated with west-facing slopes. This re ects other studies that have found associations of E. tages with south-facing slopes in the UK (Dickins et al 2013). Our result implies that this is a true re ection of E. tages preference, rather than of their foodplant's habitat association.…”

Species often associate with specific habitat characteristics, resulting in patchy distributions, whereby they only occupy a proportion of available habitat. Understanding which characteristics species associate with is a valuable tool for informing conservation management. We investigated the habitat associations of eleven species of day-flying Lepidoptera larvae and their foodplants within calcareous grassland reserves in Bedfordshire, UK, across two scales relevant to land managers and target species: the reserve (cardinal aspect, vegetation type) and foodplant patch scale (foodplant height and density). We investigated whether ecological traits (habitat specialism and overwintering life stage) influenced the strength of associations. At the reserve scale, we found variation in habitat associations across species, with species that overwinter at non-adult life stages having more restricted associations, indicating that they may be more vulnerable to environmental change. Associations were generally stronger with vegetation type than aspect, which can be manipulated more easily by land managers. Seven species had similar habitat associations to their foodplants, implying that management to benefit foodplants will also benefit larvae. However, the remaining four species had different habitat associations to their foodplants, and may require alternative management approaches. At the foodplant patch scale, four species were associated with foodplant characteristics, which could be used to inform effective fine-scale management.

“…Oviposition‐site selection is a hierarchical process that operates at several spatial scales, each of which provides different cues that the females may respond to (Vinson, ; Visser, ; Dickins et al., ; Martínez et al., ). In our study, host‐plant preferences for oviposition and feeding by T. peregrinus females were not tightly correlated, suggesting that different criteria mediate each of these selection steps.…”

Optimal foraging and optimal oviposition are two major forces leading to plant selection by insect females, but the contribution of these forces to the host-selection process has been little studied for sucking herbivores. We studied feeding and oviposition behavior of a global pest, the bronze bug, Thaumastocoris peregrinus Carpintero & Dellap e (Heteroptera: Thaumastocoridae), using dualchoice bioassays to evaluate the preference of females between host species, developmental leaf stage, or prior plant exposure to conspecifics. We assessed the link between these preferences and the performance of the offspring, by comparing survival and developmental time of nymphs reared on the various treatments. Finally, we compared the composition of the leaf wax of healthy and damaged leaves, and tested the effects of leaf wax on female preference behavior. Using healthy adult leaves of Eucalyptus tereticornis Sm. (Myrtaceae) as a reference, we found that females prefer to feed on Eucalyptus grandis W. Hill ex Maiden and E. tereticornis adult leaves that had been previously damaged by female conspecifics, whereas they reject juvenile leaves of E. tereticornis as food. Females also prefer to oviposit on leaves previously damaged by conspecifics but they rejected E. grandis as oviposition substrate. Nymphal performance varied among leaf treatments, suggesting a correlation with oviposition preference (but not feeding preference). Epicuticular wax extracts from damaged leaves contained higher concentrations of long-chain, saturated linear alkanes, aldehydes, and alcohols than extracts from undamaged leaves. However, a choice assay failed to demonstrate an oviposition preference based on leaf surface wax chemistry. We discuss these findings in the context of the preference-performance relationship.

“…We measured the aggregation or lumping of patches using AI and patch complexity with MSI. We compared landscape metrics between years using a Kruskal-Wallis one-way variance analysis with a significance level of 0.05 due to unequal variances and non-normal distributions (Dickins et al 2013).…”

Introduction: Tanglehead is a grass native to southwestern US rangelands; however, its prevalence as a native invasive on South Texas rangelands has increased rapidly during the last decade. Large areas of monotypic stands have emerged in Jim Hogg, Duval, Brooks, and Kleberg counties. The aim of this research is to understand the spatial and temporal dynamics of these invasions as a model for the assessment of native invasive species. Our specific objectives were to (1) evaluate the feasibility of classifying tanglehead using 1-m resolution imagery data, (2) assess the spatial and temporal distribution of tanglehead in relation to soil type and distance from roads, and (3) quantify the temporal and spatial distribution of tanglehead on our study sites. We combined remote sensing approaches with landscape metrics to quantify the spatial and temporal distribution of tanglehead in five locations across our study area. We calculated the normalized difference vegetation index and combined it with the original aerial imagery to conduct an unsupervised classification with the following land cover classes: woody vegetation, tanglehead, non-tanglehead herbaceous, and bare ground. Soil type and the distance from roads were assessed to determine the relationship between these factors and tanglehead spatial distribution. Results: We were able to successfully map tanglehead using the 1-m imagery. Our image classification approach resulted in accuracies greater than 85% for all sites. Tanglehead occurred in sandy, loamy sand, and sandy loam soils. Over 70% of tanglehead cover occurred within the first 150 m from the edge of roads. This cover increased from 7.1% (SE = 1.1%) in 2008 to 17.8% (SE = 5.4%) in 2014. Once established, small patches of tanglehead began aggregating or coalescing with existing stands, thereby creating larger patches over larger areas. Conclusions: Our study has shown the value of analyzing spatiotemporal dynamics of tanglehead with remote sensing techniques and landscape metrics to improve our understanding of establishment and dispersal processes of a native invasive. This study provides useful information to improve rangeland management decisions as well as assessing native invasive dynamics with potential applications for assessing its effects on wildlife habitat, livestock operations, and habitat restoration strategies.
